Alright, so there are a lot of different ways that you can treat GERD, or acid reflux. Lifestyle changes are probably the easiest thing that you can do on your own. So, if you do have acid reflux, it's important to watch your diet, because there are a lot of foods that can trigger those symptoms. So foods that are high in fat, low in fiber, high acidity or citrus foods, alcohol, sometimes smoking can also trigger acid reflux. Sleeping on a wedge helps to decrease the acid washing up to the esophagus during the night while you're sleeping.
If you do have symptoms that are not helped with those changes of behavior, then you might want to try some of the medications that you can get over the counter. The common ones are antacids such as Maalox or Mylanta, the H2-blockers such as Pepcid and Zantac, or the proton-pump inhibitors, which are very popular these days, such as Prevacid or Prilosec.
Long-term use of these medications really needs to be managed with you and your doctor. So it's important to talk to your doctor if you've had symptoms for a very long time.
